Appendix B
Allow Slow Flow
The machine may be calibrated to run at dialysate flows as low as 100 or 200 ml/min, but this
option must be selected in Service Mode and additional calibration is required.
Kt/V Graph Tolerance
In order to give an option to the user that is compatible with the 2008H machine, a selection
is available that sets the value as a minimum acceptable value for Kt/V (0% tolerance) instead
of the original target where a –15% tolerance was allowed.
Kt/V Default
The default Kt/V (target or minimum value) is now selectable in the Service Mode.
Language
The operating screens may be setup so that they are in either French (Canada), Spanish
(Mexico), or English (USA). Service Mode is always in English.
Arterial and Venous Pressure Limits
The width of the venous and arterial pressure windows are set by these options. The
windows may be set to a fixed width for all treatments or the user may be allowed to set the
limits for each treatment in the Test & Options screen. The arterial window may be set to a
total width of 120, 160, or 200 mmHg. The venous window may be set to for
100 asymmetric, or 120, 160, 200 mmHg width. If 100 asymmetric limits are chosen, the
lower venous limit will tighten to the selected value after a short time delay. This value is
selected with the "100 Asymmetric Limits" parameter entry button in Service Mode. The
choices are 20, 25, 30, 35 mmHg. The lowest value that does not cause frequent nuisance
alarms should be chosen.
Online PHT
The online pressure holding test (PHT) is enabled or disabled with this button. Normally, the
PHT should be set to "Yes".
Arterial Chamber
This option is used to define whether the arterial chamber is pre-pump or post-pump. The
range of the display is different depending on the location of the chamber.
